Question: Using the definitions for total chain molecule length, L (Equation 14.11) and average chain end-to-end distance r (Equation 14.12), for a linear polyethylene determine: (a)

Using the definitions for total chain molecule length, L (Equation 14.11) and average chain end-to-end distance r (Equation 14.12), for a linear polyethylene determine:

(a) The number-average molecular weight for L = 2500 nm;

(b) The number-average molecular weight for r = 20nm.

L = Nd sin (14.11) r = dVN (14.12)
